llnirrnn Staines Partnr trice IMPROVEMENT IN 'MOUNTING ORDNANCE.

Specification forming part of Letters Patent No. 3,@D, dated April 7, 1863.

T0 LZZ whom it 77mg/ concern: I

Be it known that I, B. H. BAR'roL, oi' Ihiladelphia, Pennsylvania, have invented a new Improved Modeof Mounting Ordnance; and

I do hereby declare the following to be a full, clear, and exact description of the same, ret`- erence being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in mounting a gun on a carriage arranged to traverse suitable tracks on a supplementary carriage, the latter being arranged to traverse segmental tracks on a turn-table, and the whole being arranged and operating, substantially as described hereinafter, for attaining such a ready and variable lateral adjustment of the gun as to enable me to use it in connection with a fixed battery, and to obtain the advantages and obviate the disadvantages of a rotating battery.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings,

which form a part of this specification, Figure l is a plan View of an iron-clad battery, illustrating my improved mode of mounting` guns within the same; Fig. 2, a transverse section of Fig. l.

The battery as shown in Fig. 1 of the drawings is of an elongated form, with straight sides and semicircular ends, inclosing suftlcient space for the accommodation and proper working of three guns mounted according to my improvement. The battery may be considered as applied either to the deck of avessel or used in connection with permanent i'ortications. battery, Fig. 2, are plated with iron of suitable strength, the roof B, on which there may be shot-proof gratings at suitable intervals, being also sufficiently protected by plates.

C represents a portion ofthe deck of a vessel; or it may be supposed to represent part of the foundation of a permanent 'ortiiication.

D is a circular platform or table, from the under side of which a central pin, cl, projects into the deck or foundation B, the table being furnished near its outer edge with any suitable number of rollers e e, which bear on a circular track secured to the deck. In the present instance, three turn-tables are ar The inclined wooden sides oi' the.

ranged within the elongated battery, the center of rotation of each of the end tables coinciding with the center of one of the semicircular ends of the battery, and the third table being situated midway between the other two. Each semicircular end of the battery has in the present instance iive ports, j', and each side has one for the central gun, every port being sufficiently wide to admit the muzzle of the gun and of sutlicient Vlength to allow the muzzle to be raised and lowered to the desired extent, and each port being beveled, as shown in Fig. l, so as to allow for a limited lateral adjustment ofthe guns.

The gun E is mounted on a carriage, F, which is furnished with wheels arranged to traverse the ribs c a of the supplementary' carriage G, the latter having on each side projecting lugs, to which are hung the wheels H and H, the front wheels, H lil, being ar ranged to traverse the segmental track I, and the rear wheels, Irl and I-I, to traverse the segmental track I. AThese tracks form the seg ments of circles having a common center, which is at a point, a', midway between the opposite sides of one of the port-holes and near the outer surface of the battery.

The carriage F, with its gun, may be readily moved along the ribs of the supplementary carriage G, and drawn within the battery prior to being loaded, and may be as readily moved out, so that the muzzle of the gun may project to the desired extent through one of the port-holes prior to the discharge of the load.

Independently of the removal of the gun from one port-hole to another, which may be accomplished by simply turning the table D, it can be made to radiate on the point .r as a center by causing the wheels ofthe supplementary carriage G- to traverse the segmental tracks I and I. Thus the gun E can be so adjusted as to discharge a shot either in the direction ofthe line in or that of the line n, or

in any direction between these two lines,

without the necessity of moving it from one port-hole to another.4

It will be evident that the battery, with its readily-available guns, is as effective as a ro tating battery, While the complex and heavy mechanism required to operate the latter is obvia-ted.

l segmental tracks on a turntable, D, substan. tally as and for the purpose herein set forth. l In testimony whereof I have signed my nanie to this specification in the presence of two sub- -scribing` Witnesses.
